RAIL-ANCHOR. H

arly to a device conveniently applicable to' rails generally and without alteration thereto.

An object of the present invention is to provide a rail anchor embodying relatively movable rail engaging elements, one of said elements being adapted to contact an adjacent tie to prevent creeping of the rail thereon.

The invention further proposes a rail anchor in which means of novel construction and arrangement are provided for locking the rail engaging elements in clamping relation to the rail.

With the above and other objects of similar nature in view, the invention consists in the construction, combination and arrangement of parts, set forth in and falling within the scope of the appended claims.

in the drawings: Figure 1 shows a section of rail and its ties with the invention applied; Fig. 2- is a side elevation of the anchor with the rail in section; Fig. 3 is a sectional view taken on the line of Fig. l; and Fig. l is detail perspective view of the locking collar removed.

lhiferring now more particularly to the accompanying drawing, there is shown a rail A and ties B of ordinary construction.

The invention is designated generally at and comprises a shank having formed integrally therewith at one end an enlargement or head 6 transversely grooved as at 7, while its other end is of substantially T- shaped formation, produced by casting upon its sides oppositely directed lugs 8. Loosely engaged upon the shank 5 is a movable clamping member 9 preferably in the form of casting provided with a groove 10 opening toward the groove in the head 6 and adapted to coact-therewith in securing the anchor to the rail A.

The member 9 is formed at one side with Specification of Letters Patent. Patented Ji in. ltd, 191i Ti.

Serial No. 105,421.

an enlargement 11 having a flattened face 12 disposed at right angles to the groove 10 and adapted to bear against the adjacent tie B, as clearly illustrated, whereby to prevent creeping of the rail thereon. The member 9-is further transversely apertured as 13 to receive the shank 5 and has pro vided inthe wall of said aperture at diametrically opposite points, recesses 14 shaped to conform to the lugs 8 whereby to permit its convenient engagement with or disengagement from the shank. Loosely engaged on the shank 5 outwardly of said member is a washer l5 likewise apertured as at 16 to correspond to the T-shaped end of the shank 5 so as to readily be applied to or removed from the latter.

For locking the anchor to the rail, there is provided a collar 17 centrally apertured as at 18 to receive the shank and provided in the wall of the aperture with oppositely opening recesses 19 arranged to receive and readily pass over the lugs 8. Formed in the outer face of the collar 17 and extending in a corresponding direction from the recesses 19 are a pair of cams 20, terminating at pointsremote from the related recess, in

pockets 21 countersunk in the face ofthe collar. These pockets are adapted to receive therein the lugs 8 and when so positioned the collar 17 will be securely held against rotation in either direction on the shank.

In applying the anchor to the railA it is clamped beneath the base of the latter and adjacent one of the ties B, the groove 7 in the head 6 of the shank being engaged with the inner base flange, while the member 9 is passed over the T-shaped end of the shank and moved to en gage the outer base flange of the'rail. The. washer 15 is next engaged upon the shank outwardly of the member 9. and finally the collar 17 is passed over and beyond the lugs S to rotatably receive the shank and bear against said washeiu In order to secure the parts in their relative positions, the collar 17 is rotated on the shank, by means of a wrench or other tool applied to the faces 22 thereof provided for the purpose. Such movement of the collar will serve to engage the cams 20 behind the lugs 8 and consequently force the member 9 and head 6 into clamping relation to the rail. It is apparent that continued rotation of the collar will bring the pockets 21 into 1 registration with the lugs 8 so that the latter will spring into the same and be held in such position by the expansive tendency of the parts. The anchor is thus positively held against movement With respect to the rail A, While the flattened face 11 of the member 9. which is dis 30S8d in en a ement with the i adjacent tic, will prevent creeping of the rail thereon.

What is claimed is l. A cam lock comprising the combination with a shank having laterally extending lugs at one end, of a collar centrally apertured to pass over said lugs and rotatabiy engage the shank, cams formed on the outer face of the collar to engage behind the lugs and pockets in said collar adapted'to receive the lugs and prevent relative rotation of the shank and collar in either direction.

2. A rail anchorcomprising a shank having a grooved head at one end adapted to engage the base of a rail, oppositely directed lugs formed on the other end of the shank, a member loose on the shank adapted to engage said rail base and an adjacent tie to prevent creeping of the rail thereon, a Washer on the shank outwardly of said member, a collar on the shank, cams formed on the outer face of the collar to engage behind the lugs, and pockets in said collar adapted to receive the lugs and hold the shank and collar against relative rotation, said collar, washer and member being similarly apertured to pass over said lugs for engagement with or disengagement from the shank.

In testimony whereof, I atlix my signature. in the presence of two Witnesses.
